Members of a University of Tokyo team said they developed a robot that wins every game of rock-paper-scissors by employing split-second reflexes.

The team from the university's Ishikawa Oku Laboratory said the Janken robot, named for the game's Japanese name, uses high-speed recognition and reaction to respond to its opponent's throw so quickly that the human eye perceives it to be forming hand shapes at the same time as a human opponent, the BBC reported Monday.
